ABSTRACT

The choice of an appropriate method for rare earth element (REE) preconcentration from industrial by-products is a very difficult task. Most of the REE separation reviews focus on liquid extraction methods, whereas sorption processes are usually mentioned in connection with chromatographic individual REE separation. Limited information is currently available on ion exchange methods for REE preconcentration. The REE sorption methods are gradually acquiring great practical significance due to depleting REE sources. The present review deals with the history, recent studies and commercial applications of REE sorption from various complex industrial by-products such as products of apatite treatment, phosphogypsum and uranium ores. It covers an extensive study on the recent research related to use of polymeric ion-exchange sorption materials for REE preconcentration and recovery from various industrial wastes.

摘要

从工业副产品中选择合适的稀土元素 (REE) 预富集方法是一项非常艰巨的任务。大多数 REE 分离评论都集中在液体萃取方法上，而吸附过程通常与色谱单独 REE 分离有关。目前关于 REE 预浓缩的离子交换方法的信息有限。由于稀土资源的枯竭，稀土吸附方法逐渐具有重要的现实意义。本综述涉及从各种复杂的工业副产品（如磷灰石处理产品、磷石膏和铀矿石）中吸附 REE 的历史、近期研究和商业应用。
